Auxiliary packaging part



Nov. 3, 1936. A. F. FILES AUXILIARY PACKAGING PART Filed Dec. 15, 1955 Q6/0269 J QZWL Patented Nov. 3, 1936 UNITED STATES PATENT OFFICE AUXILIARY PACKAGING PART Adino F. Files, Maumee, Ohio Application December 13, 1935, Serial No. 54,310 4 Claims. (01. 206-47) My invention has for its object to provide a member that may be readily positioned with reference to the cover or closure element of a package or container, and which is provided with engaging parts that engage the cover or closure element of the package or container to open the package or container upon withdrawal of the member. Preferably the member is made in the form of a packet for containing articles or material and used as an auxiliary packaging part.

Thus, the invention provides .a simple and efficient means whereby a packet having engaging parts may be readily inserted in position in a container having a cover member or movable closure part, and will be quite securely sustained in the position in which it is placed and will, upon with drawal from the said position, operate to open the main package.

The invention is of particular value when used in connection with a carton having the closure parts comprising a flap and a tongue. The tongue is formed to be inserted within the container and along one side for maintaining the flap or cover part in its closed position. The member or packet is readily insertable intermediate the tongue and the contiguous side of the container to locate the .engaging means in engaging relation with the edge of the tongue. Thus the member or packet operates, when withdrawn, to withdraw the tongue and. swing the flap to an open position.

The opening member or packet of my invention may be varied in the details of its structure, and when in packet form, may be used for containing materials and articles of different kinds.

The preferred forms of the structures, which are selected as examples of embodiments of the invention, are shown in the figures of the drawing and are described hereinafter. 4

Fig. 1 illustrates an enlarged perspective view of the packet that may be used as an auxiliary to a butter carton of the conventional type. Fig. 2 illustrates the packet in position with reference to the tongue of the cover or end flap of the carton. Fig. 3 illustrates a greatly enlarged view of a section taken diagonally through one of the corners of the packet. Fig. 4 illustrates an en.- larged broken View of a modified form of packet and shows one edge part of the packet, it being understood that the four edge parts of the packet are the same. Fig. 5 is a view of a section taken on the plane of the line 5-5 extending diagonally through one of the corners of the packet shown in Fig. 4.

The member I is preferably flexible in character. It may be laminated to give rigidity to the engaging parts and yet produce pliability in the body of the member. Thus, the sheets 3 and 4 are secured together by a cementitious material. The engaging parts may be formed while the cement or glue is still plastic, which will render them rigid and substantially positive in their engagement when the cement or glue hardens. Where the member is used as a packet for containing material, the cement may be disposed intermediate contiguous marginal portions of the surfaces of the sheets as indicated in Fig. l, the cementitious material being disposed intermediate the dotted line 5 and the edges of the sheets.

The material is located centrally, and the sheets may be secured together by means of the cement or glue 1 along the marginal parts of the sheets to enclose the centrally disposed contents. The sheets may be formed of any suitable sheet material, and the cementitious material may be varied according to the character of the material of which the sheets are formed.

The packet may be oblong or rectangular or circular in form. The engaging parts are preferably spaced from each other to enable engagement of one or more of the engaging parts. In one of the forms of structure illustrated in the drawing, pin point projections B are formed in the corner parts of the packet, preferably within the area of the marginal parts in which the cementitious material is located, which produces by reason of the cementitious material, as well as by reason of the laminated arrangement of the portions of the layers that are deformed in forming the projection, exceedingly rigid protu- 35 berances that will engage parts of an article, such as the edges and corners of the cardboard of which cartons are usually formed, and prevent or limit relative sliding movements of the packet and retain the packet in position. Also, the pin points operate to space edge portions of contiguous packets that may be piled and enable ready handling of the packets. Where a relatively small amount of material is used, as is common in connection with the type of packet illustrated in Figs. 1 and 4, the pin points operate to space the marginal parts of the packet substantially the same distance that is produced centrally by the disposition of the material in the central part of the packet, thus enabling piling and convenient handling of a plurality of sets of packets.

The pin points are formed by a suitable pointed instrument that may be suitably mounted in a machine for sequentially forming or punching pointed projections from the corners of the packets. In the formation of the packet, the material is disposed centrally on one sheet and covered by another sheet, either sheet having cementitious stripes formed or deposited marginally thereon, as by roller printing or otherwise. The sheets are then pressed marginally to secure them together. The pin points may be formed in the corners of the packets while the cementitious material is still semi-liquid or plastic and produce thereby relatively rigid projecting pin point protuberances when the cement hardens. The packet may be inserted in a container of material or articles with which the contents of the packet is associated or in connection with which it is to be used, so as to locate an edge portion of the packet where it will readily appear and will be readily retained by the projecting parts. It may be located in a position so that the projections will engage an edge of the cover or the closure member of the container, and will then operate to pull the cover member open when the packet is withdrawn.

Where the container is a carton of .the type commonly used for containing butter and oleomargarine, the packet may contain a butter or oleomargarine coloring material, and may be readily slipped intermediate the tongue l2 of the cover or end part l3 of the cardboard blank of which the carton I is formed, so as to dispose any one or more of the pin points in engaging relation with the edge of the tongue l2 and, preferably, so as to locate a portion of the packet exterior tothe carton I 0. When, therefore, it is desired to color the butter or oleomargarine or to use the material or article of the packet in conjunction with the material or article of the container, the packet may be withdrawn to open the carton.

If desired, the packet may be provided with tongues I6 as in the form of the packet l'l shown in the Figs. 4 and 5. The tongues l6 may be cut from the corners of the packet and deflected from the plane of one of the surfaces of the laminated portions of the sheet material of the packet. The tongues may be out, if desired, while the cement is still liquid or semi-plastic, which will operate when hardened to secure the tongues in their bent or deflected positions. Preferably the longitudinal axes of the tongues are located diagonally with respect to the edges of the packet whereby any two of the four tongues located in the corners of the packet may be disposed within a carton and will engage the edge of a cover part to open the carton when the packet is removed from the carton, substantially in the same manner that the protruding portions on the corners of the packet shown in Figs. 1, 2, and 3 will open the end flap of the carton I 0.

I claim:

1. In combination with a carton formed from a blank having an end flap and tongue, the flap forming a closure member of the carton, the tongue connected to the flap and located within the carton and disposed contiguous to an end part of the side of the carton, a member having a ,plurality of pointed projections disposed in spaced relation and insertable intermediate the tongue and the said side of the carton, the pointed projections operative to retain the member in position and adapted to engage the edge of the tongue upon withdrawal of the member and open the cover part.

2. A packet formed of at least two layers of flexible sheet material and having marginal parts cemented together, the central parts forming a chamber for containing material sealed within the layers by the cemented marginal parts, the marginal parts having spaced projecting portions extending beyond the plane of the central material enclosing parts of the layers of sheet material, the projecting portions rendered rigid by the hardening cement and operative to space edge parts of compiled packets.

3. A packet formed of two layers of flexible sheet material and having marginal parts cemented together, the central parts forming a chamber for containing material sealed within the layers by the cemented marginal parts, the marginal parts having protruding tongues cut from the cemented marginal portions and secured in their protruding relation by the hardening of the cementitious material, the tongues inclined inwardly from the marginal portions and their ends extending toward the central portions of the packet and protruding towards one side of the packet.

4. In combination with a container formed from a blank and having a cover part hingedly connected to one side of the container and having a portion that is located in proximity to the opposite side of the container for closing the container, a packet formed of at least two layers of flexible sheet material and having marginal parts cemented together, the central parts forming a chamber for containing material sealed within the layers by the cemented marginal parts, the marginal parts having spaced projecting portions extending beyond the plane of the central material enclosing parts of the layers of sheet material, the packet located intermediate the said portion of the cover and the said opposite side of the container, the projecting portions of the packet operative to engage the said portion 01 the cover for retention of the packet in position and adapted when pulled from the container to engage the said portion of the cover to move the cover to open the container and at the same time withdraw the packet from the container.
